SNAS548C –FEBRUARY 2000–REVISED MARCH 2013

LM555 Timer

Check for Samples: LM555

FEATURES

DESCRIPTION

The LM555 is a highly stable device for generating

accurate time delays or oscillation. Additional

terminals are provided for triggering or resetting if

desired. In the time delay mode of operation, the time

is precisely controlled by one external resistor and

capacitor. For astable operation as an oscillator, the

free running frequency and duty cycle are accurately

controlled with two external resistors and one

capacitor. The circuit may be triggered and reset on

falling waveforms, and the output circuit can source

or sink up to 200mA or drive TTL circuits.
